Does Racket’s module path string support &? I created an empty module module-&.rkt on windows 7, then typed in REPL: E:\work-pl\racket\code\module\module-path-string>racket Welcome to Racket v8.0 [bc]. > (require "./module-&.rkt") ; stdin:1:9: require: bad module-path string ; at: "./module-&.rkt" ; in: (require "./module-&.rkt") ; [,bt for context]

No, & is not allowed in a collection-based module path. You can use file if you don’t care about collection-based paths and just want to refer to a file: (require (file "./module-&.rkt")).

@mflatt Thanks!

Does & do something interesting or is it just another character?

I use & for short name of and (just in some experimental code).
